Vegan Gluten-Free Funfetti Mug Cake Recipe

This vegan Funfetti Mug Cake is moist, fluffy and full of vanilla flavour! Incredibly quick and easy to make in the microwave with simple ingredients. (Eggless, Dairy Free, Gluten Free + Oil Free)

Happy Friday and welcome to day 5 of mug cake week! It doesn’t get much more cheerful than funfetti — bright sprinkles and vanilla cake that tastes like a tiny celebration in a mug.

Vanilla mug cakes are often tricky to perfect, especially for texture, but this vegan Funfetti version turns out moist, tender and fluffy using simple pantry ingredients. It’s fast, healthy-ish and great for breakfast, dessert or whenever you need a sweet pick-me-up. Here’s what you’ll need:

  • Tahini or cashew butter: Replaces oil and butter. Cashew butter works well if it’s the runny variety.
  • Oat flour: This cake is made with oats, so feel free to enjoy it for breakfast. If you don’t have oat flour, all-purpose flour is an easy substitute.
  • Apple cider vinegar + baking powder: With no eggs, this acidity-and-leavening combination helps the cake rise and stay light.
  • Granulated sugar: Coconut sugar keeps the recipe refined-sugar free but will darken the cake slightly. Use white granulated sugar or cane sugar if you prefer a classic pale cake color.
  • Vanilla + almond extract: Vanilla is essential; a touch of almond extract elevates the flavor (optional but recommended).
  • Funfetti sprinkles: Optional for flavor but necessary for the true funfetti look.

How to Make Funfetti Mug Cake

If you’re new to mug cakes or haven’t tried my other recipes, here’s a quick, foolproof method to make this speedy vanilla mug cake in the microwave:

  1. Add the wet ingredients to a 10 oz microwave-safe mug or a deep bowl and stir until well combined.
  2. Add the dry ingredients and stir until a cupcake-like batter forms. If the batter seems too thick, add 1–2 teaspoons more non-dairy milk. Fold in the sprinkles if using.
  3. Microwave on high for 1 minute. Rotate the mug and microwave for another 20–30 seconds to ensure even cooking and prevent a lopsided cake.

Let the cake cool for 2 minutes — it continues to set as it rests. Top with dairy-free whipped cream, dairy-free ice cream, a drizzle of frosting, and extra sprinkles for an extra festive touch.

Texture check: moist, fluffy and perfectly vanilla. Sprinkles make everything more fun and pretty, and this cake proves you don’t need a full oven (or a whole cake) to celebrate.

It doesn’t have to be your birthday to enjoy a personal Funfetti celebration — make one whenever you want a cheerful, single-serve treat.

Description

This vegan Funfetti Mug Cake is moist, fluffy and full of vanilla flavour! Incredibly quick and easy to make in the microwave with simple ingredients. (Eggless, Dairy Free, Gluten Free + Oil Free)


Ingredients

  • 1 tbsp cashew butter (15g) or 1 tbsp tahini
  • 3 tbsp non-dairy milk (45ml)
  • 1 tbsp granulated sugar (12g)*
  • 1/2 tsp apple cider vinegar
  • 1/2 tsp vanilla extract
  • 1/4 tsp almond extract (optional)
  • 1/4 cup oat flour (30g), homemade or store bought
  • 1/2 tsp baking powder
  • small pinch of salt
  • 1 tbsp vegan funfetti sprinkles (10g)

Topping:

  • Coconut whipped cream
  • Dairy-free ice cream
  • Extra vegan sprinkles

Instructions

  1. Add tahini or cashew butter, non-dairy milk, apple cider vinegar, vanilla, almond extract (if using), sugar and a pinch of salt into a microwave-safe 10 oz mug or deep bowl. Stir until combined. Sift in oat flour and baking powder, then stir until just mixed. If the batter is too thick, add 1–2 tsp more non-dairy milk until it resembles muffin batter. Fold in the funfetti sprinkles.

Notes
